Mechanized feller-bunchers have been used very effectively in the Interior of British Columbia. Exco Industries Ltd. of 100 Mile House, British Columbia has recently introduced an improved version of the Lokomo cone saw felling head that has the ability to accumulate several trees during felling (Figure 1). The Forest Engineering Research Institute of Canada (FERic) observed a Lokomo L6000 cone saw operat- ing in the early spring of 1991.
